- a l cation-tiedSe tember 17;;192'0. seiiai-noi'noisis.-'E 1 Myinvention relates to a system file, theprimary object of which is toprovide means for collectively holding correspondence consisting ofletters and: other papers in a col:

lapsible file concealed in a neatand tidy manner so that instead of theoflice desk be- .ing mussed-up with papers they can be held together inan adjustable file under. aparticular index readily accessible-whendesired. I

p The invention consists of filing means which is collapsible into afiat'thin state when empty, primarilydesigne'd to he used inconnection'with an oflice desk and having self-adjusting means tovarious thicknesses to accommodate letters andpapers beneathseparatesheets in a file which isadapted .to hold the'same collectively. Thismeans of keeping correspondence papers upon which immediate" actionis'desired affords .a very d'esirablefoflice utility and has a tendencyto systematize the routine of WOIk of the user. A file of this nature isadapted'torece'ive considerable use'anda featurejof the inveiit on ismproviding avery substantial manner in securing the-dividing sheets tothe main back of the file'so thatthe strain' either from pulling"directly against the 's'heets or the wear of folding the sheets over ontheir hinged-edge Will not loosen the sheets'from the back, whichwould'very likely happen unless the'sheets were attachedyin thepeculiarmanner in which I have illustrated in myinvention. i: It is essentialiSO'PIOVIClE a substantial file,

The labelholder 16 is attached in a suitable manner to the corners of eiaxchsheet and to the cover of the system file f r The sheets 10 have theirfree ends covered with a piece of leather 19 or other suitable Wellwearing material to protect these ends which receive a good deal of wearby handling and when the file is in use the free ends of the sheetsproject one below the other in consecutive order sothat the ends of eachsheet is exposed from beneath the end of the cover 14. This is true ofthe sheet even when the file is in use with papers between the same, asthe portion 12 tends to extend on a slant and thus expose the free endsof the sheets. V

Each of the sheets 10 are formed with a series of oppositely projectingtongues 20 and 21 respectively, which are glued or otherwise attached tothe inner surface of the portion 12 to securely'attach the sheets in thefile. By this peculiarconstruction any direct pull on the sheets 10 istransmitted to either side of the hinged edge 22 of each of the sheets,thus venly distributing the strain on either side of the'sheet andtending to form a strong attaching means for the sheets. The tongues 20and 21 mesh with each other as illustrated in Figure 3 so as to give aflat engaging-attaching means at the hinge of each sheet and preventbulging of the sheets at the hinging point when the file is folded orcollapsed.

lVhen the system file A is in use it simulates a parallelepiped in shapeas is illustrated in Figure 2. The file at all times adjusts itself inaccordance with the thickness of the materialinserted between the leavesof the same. It never tends to bulge pt the top where the leaves arehinged and secured together. The member 12 adjusts the position of theseparatingleaves 10 due tothe hinging of the same along the edge 13 ofthe back 11.

The separating sheets 10 are equally spaced apart and attached tothehead portion 12 of the file A. V This construction permits them to beself, or automatically adjustable when material is inserted between hemup t the max m sp e of separa tion between the points of theirattachment,

. thus papers can be inserted in the file A without'bulging the'sheetsat the hinging point up to the thickness of the space separating thesheets from the back and adjustble hea po n V I In accordance with thepatentstatutes I ha d scrib d t e prin p of per tion of my inventica oselier ith.v the con truc ion, wh h be e eto b th bes embodiment h reof,but Id re o have .it understood that the invention may be applied toother are folded together, a series of separating sheets, and meansextending from either side of said sheets along one edge thereof adapted to hingedly attach said sheetsto said interposed member in a mannerto secure said 7 sheets on either side of the line ofhinging thereof tosecurely hold them to said back.
